SimLas is a system for testing, developing and calibration of Lidars. SimLas is designed for reproducible and precise simulation of the environment of Lidars in the lab. It can in real time simulate reflections from different distances and surfaces to mimic real environment. SimLas enable engineers to test their Lidars during the development phase as well as test the capabilities of Lidars before their integration in the complex sensing systems.

The working principle

The SimLas works with real Lidar sensors. It receives the optical pulse from Lidar and generates an echo pulse or multiple echo pulses which are sent back to the receiver of the Lidar. SimLas enables deterministic control of the following relevant parameters of the Lidar sensor.

• Delay of echo pulse: simulates the distance to the reflecting object
• Attenuation of the echo pulse: simulates various reflections from different surfaces.
• Additional noise in optical signal: can be used to simulate atmospheric conditions

Possible use cases

with SimLas, Lidars can be tested and calibrated in the laboratory in fully deterministic and reproducible conditions. This is possible due to very reliable and precise echo pulse generation which can be combined with various scenario generators.

Whether one needs traffic simulation for automotive Lidar sensors or environment simulation for industrial Lidars SimLas will enable accurate stimulation of the Lidar with precise repeatability. Due to its high stability and reliability SimLas can also be used to calibrate Lidars and test auto calibration strategies in dynamical environment. SimLas can also be used for simulation of weather conditions, e.g. rain or snow, in fully reproducible way.
